摘要
In total, 185 wheat cultivars and lines from major Chinese wheat regions, Australia and USA in two trials, sown in four and two environments, respectively, were used to investigate starch property and its relationship with dry white Chinese noodle (DWCN) quality. Significant variations were observed in all starch parameters and DWCN quality. High pasting viscosity cultivars include Sunstate, Hartog, Eradu, Cunning-han, Gamenya, Karl92, Sunco, Yangmai5, Yangmail58, Mianyang26, Een1, Yumai41, Yumai49, Zheng81-1, Yumai54, Yumai2. Yumai47, Lu955159, Lumai15, Lumai21, Shaanyou225, Guanfeng2, Ji5099, Bainong4, and Jinmai2. Wheats from Australia, USA, South China Autumn-sown Spring Wheat Region and Yellow and Huai Valley showed better starch properties and DWCN quality than those from North China Plain. High peak viscosity, breakdown and flour swelling volume were significantly associated with good DWCN quality. A relatively high frequency of Wx-B1 null alleles was detected in Chinese wheats. Cultivars with null for Wx-Bl GBSS performed higher pasting viscosity and flour swelling volume, and better DWCN quality than normal type.
